Local Group
group of galaxies that includes the Milky Way / From Wikipedia, the free encyclopedia
The Local Group is the group of galaxies that includes our galaxy, the Milky Way.
The group has more than 50 galaxies (including dwarf galaxies). Its center of mass is somewhere between the Milky Way and the Andromeda galaxy. The galaxies of the Local Group cover a 10 million light-year diameter and have a binary (dumbbell) shape. The group has a total mass of about (1.29 ± 0.14)×1012Ms.[1] The group itself is part of the Virgo Supercluster (also called the Local Supercluster).[2]
